While not so much in residential work (except for sidewalks), very often control joints are added to the concrete to essentially "control" where the concrete cracks (i.e., attempting to force the shrinkage cracking to follow the control joint to it looks orderly and straight).  

My properties in rent control I just do minimal upgrades to and let them sit while my non-rent controlled properties I constantly fix up and try to improve constantly.  

How should I go about doing a joint venture(paperwork etc)?

I was approached by another investor who wants to complete a joint venture with me.  

I don't want to be constantly worried about what's going on in my property and if a PM is taking advantage of me or not doing their job.

These units are near a military base (where my husband works) that sees a constant flow of airmen staying 4-9 months at a time.  

As for the BRRRR strategy, I'm good with BRR, but I would be concerned about over-leveraging with constant refinances of the full BRRRR.

The stability of this Vegas market is constantly in question.  

I asked my HVAC guy about this once and he said used units generally fall into two categories: either salvaged, working, from a site for some reason - house being torn down, storm damage, unit too big/small for the house - or the unit was a lemon and replaced because of constant problems. 

We also make sure that there are grooves on the joints where the floorboards meet (this gives a greater impression of real hardwood, beveled edges in other words).
